This 2010 book is the product of a research partnership designed to identify the “ideal” state of peace and security in Northeast Asia in 2025 and to further explore issues related to that ideal. The Mansfield Foundation partnered with the Advanced Systems and Concepts Office of the Defense Threat Reduction Agency (DTRA) and the Science Applications International Corporation (SAIC) on this project, which brought experts from Asia and the Pacific together for two 2009 workshops to identify an ideal security situation for Northeast Asia in the year 2025 as well as current and likely future trends diverging from that ideal. Scholars from throughout the region were then asked to address seven key issues related to the ideal security state for Northeast Asia in 2025 and to make policy recommendations to close the gap between current trends and the identified ideal. The book is a compilation of their papers, which address topics ranging from the impact of the global financial crisis to the implications of China’s continuing rise. A new book based on the second year of this ongoing project is available here.
